No, I have Win7. I have it set to run in a window. It is the kind of thing that I run while doing other things, like waiting on an upload, etc. It might be a DirectX issue. I can't say about Win8, but Vista/Win7 have both DirectX 9 and DirectX 10 or 11 because 10 and 11 are not backwards compatible. Try updating the DirectX 9c
